Rule Summary

This action promulgates national emission standards for hazardous air pollutants (NESHAP) for leather finishing operations. The EPA has identified these facilities as major sources of emissions of hazardous air pollutants (HAP), such as glycol ethers, toluene, and xylene. These NESHAP will implement section 112(d) of the Clean Air Act (CAA) by requiring all leather finishing operations that are major sources to meet HAP emission standards reflecting the application of the maximum achievable control technology (MACT).
